It is isolated from foreign markets, and has some inadequate infrastructure; it lacks major natural resources, has limited manufacturing and suffers moderately from natural disasters. Tourism provides the economic base which makes up approximately 67.5% of GDP. Additionally, the economy is supported by foreign aid, largely from New Zealand. The Peoples' Republic of China has also contributed foreign aid which has resulted in, among other projects, the Police Headquarters building. The Cook Islands is expanding its agriculture, mining and fishing sectors, with varying success. Since approximately 1989, the Cook Islands have become a location specialising in so-called asset protection trusts, by which debtors, or those fearful of becoming debtors, seek to shelter assets from the reach of creditors. The Cook Islands is a representative democracy with a parliamentary system in an associated state relationship with New Zealand. Executive power is exercised by the government, with the Chief Minister as head of government. Legislative power is vested in both the government and the Parliament of the Cook Islands. There is a pluriform multi-party system. The Judiciary is independent of the executive and the legislature. The Head of State is the Queen of New Zealand, who is represented in the Cook Islands by the Queen's Representative. The islands are self-governing in "free association" with New Zealand. New Zealand retains primary responsibility for external affairs, with consultation with the Cook Islands government. Cook Islands nationals are citizens of New Zealand and can receive New Zealand government services, but the reverse is not true; New Zealand citizens are not Cook Islands nationals. Despite this, as of 2011, the Cook Islands had diplomatic relations in its own name with 34 other countries. The Cook Islands is not a United Nations member state, but, along with Niue, has had their "full treaty-making capacity" recognised by United Nations Secretariat, and is a full member of the WHO and UNESCO UN specialized agencies and is an associate member of the Economic and Social Commission for Asia and the Pacific (UNESCAP).
